Evidence linking Pseudomys occidentalis to cats. Systematic review of evidence for an association between Pseudomys occidentalis and cats. Positive studies are in support of the hypothesis that cats contribute to the decline of Pseudomys occidentalis, negative studies are not in support. Predation studies include studies documenting hunting or scavenging; baiting studies are associations between poison baiting and threatened mammal abundance where information on predator abundance is not provided; population studies are associations between threatened mammal and predator abundance.
